BUG of the Poison magic in 97d files

I have a problem, the poison doesnt works on the test server that i start to operate with, please can you provide any explanation how can be fixed, is the GS or the client that is responsible for this poison dmg count, what i mean is when i try to poison for example the invasion, as far as i know the poison is dealing in a %dmg of the life of the creature/hero every some seconds, the problem is this poison dmg, that has to come on screen as green numbers does not apear, and also the same to the opposite, the creatures that are for example in losttower wich have to poison me don't poison, for me , this is a major problem, i really am willing to host a server that is very classic low exp and drop server, i haven't modify the invasion creatures configuration and they are very very strong, so i would like to poison them since they have very much life, it is very interesting for me what dmg would be done and if it is possible to kill at very low reset, but even if i set up the configuration to not have a reset and the invasion to be not so strong, i still am willing to operate with a server where the poison dmg works properly ,please if someone who is able of bringing clarity on this subject, i will very much appreciate, i have to apologize if there is somewhere in the past a similar topic , if possible to refer me to it if there is because i don't or don't want to beleave i am the first one encountering the issue, thank you.
